超聲波液位計用途：液位和料位測量是工業(yè)上經(jīng)常遇到的一個問題，超聲測位技術(shù)有很多優(yōu)點，它不*能定點和連續(xù)測位，而且能方便的提供遙測或遙控所需的信號。與放射性測位技術(shù)相比，超聲技術(shù)不需要防護，與激光測距技術(shù)相比，它又有簡單和經(jīng)濟的優(yōu)點，同時超聲技術(shù)一般不需要運動部件，所以在安裝和維護上又相應(yīng)比較方便。超聲波物位計可廣泛應(yīng)用于石油、礦業(yè)、發(fā)電廠、化工廠、水處理廠、污水處理站、農(nóng)業(yè)用水、環(huán)保監(jiān)測、食品（釀酒業(yè)，飲料業(yè)、添加劑、食用油、奶制品）、抗洪防汛、水文監(jiān)測、明渠、空間定位等許多行業(yè)。超聲波物位計原理：物位測量過程中，超聲波信號由超聲波探頭發(fā)出，經(jīng)液體或固體物料表面反射后折回，由同一個探頭接收，測量超聲波的整個運行時間，從而實現(xiàn)物位的測量。聲波傳輸距離與聲速和聲傳輸時間的關(guān)系可用公式表示：超聲波物位計的算式L：超聲波探頭距所測料面距離。單位：m；v：經(jīng)溫度補償后的聲速值。單位：m/s；t：測量范圍內(nèi)聲波的運行時間。 </p><p> 雷達物位計使用的注意事項介電常數(shù)的影響： </p> <p> 低介電常數(shù)和變介電常數(shù)的被測介質(zhì)，推薦導(dǎo)波雷達。低介電常數(shù)液體介質(zhì)反射信號弱，信號衰減嚴重，物位波動和泡沫散射引起信號減弱，罐內(nèi)障礙物反射引起虛假信號，為此就需要發(fā)射較強的電磁波信號，并采用功能強的微處理器進行復(fù)雜的信號處理。這就使得常規(guī)交流供電雷達物位計價格非常昂貴，但仍難以較好的解決在上述條件下的物位測量問題。導(dǎo)波雷達和常規(guī)雷達一樣，采用傳輸時間來測量介質(zhì)物位，信號自烴類[介電常數(shù)2~3]液體表面或自水[介電常數(shù)80]面反射回傳的時間一樣的，不同的只是信號幅度[強度]的差別。普通雷達須考慮介質(zhì)的影響，比較難辯識返回的各種信號，從雜散信號中檢出真正的物位信號，而導(dǎo)波雷達*需測量電磁波的傳輸時間即可，無需信號的處理和辨別。儀表的傳感器與灌壁及被測介質(zhì)形成導(dǎo)納值，電路單元將測量導(dǎo)納值轉(zhuǎn)換成物位信號輸出，實現(xiàn)物位測量。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="射頻導(dǎo)納物位計選擇,物位計"

液體、物位的測量：對于液面相對平穩(wěn)的罐體，且被測液體的介電常數(shù)較高，可以選擇普通雷達物位計。對于液面波動大、或帶有攪拌的罐體，或被測液體的介電常數(shù)較低，應(yīng)推薦導(dǎo)波雷達。因為導(dǎo)波管對液面有整型作用，且導(dǎo)波雷達的微波反射不易受環(huán)境條件變化的影響。被測液體的介電常數(shù)和密度變化對測量結(jié)果沒有影響。對于被測液體的粘度≥500cst，且液體粘附性較強的情況，不能選擇導(dǎo)波管方式測量，因為粘附和結(jié)晶會堵死導(dǎo)波管。從而形成虛假物位。可以選擇導(dǎo)波桿方式來測量。當介質(zhì)在探頭上的涂污對測量物位的影響可分為兩種：膜狀涂污和橋接。膜狀涂污是在物位降低時，高粘液體或輕油漿在探頭上形成的一種覆蓋層。由于這種涂污在探頭上涂層均勻，因此對測量基本無影響；但橋接性涂污的形成卻能導(dǎo)致明顯的測量誤差，當塊狀或條狀介質(zhì)污垢粘結(jié)于波導(dǎo)體上或橋接于兩個波導(dǎo)體之間時，就會在該點測得虛假物位。儀表可以空倉調(diào)試。在固體測量中的應(yīng)用可以使用K-頻段的高頻傳感器。高頻脈沖雷達物位計用途</p><p
